Answer: Green algae like Spirogyra.
- A Flowering angiosperms
- B Seed-bearing gymnosperms
- C Green algae like Spirogyra
- D Mosses and liverworts
Correct answer: C. Green algae like Spirogyra
Explanation: Many green algae (e.g. Spirogyra) are haplontic - the dominant phase is haploid and the diploid zygote immediately undergoes meiosis.
Plants evolved from water-dependent algae through increasingly land-adapted groups, gaining vascular tissue (Pteridophyta), then seeds (Gymnosperms), and finally fruit-enclosed seeds (Angiosperms) - each step reducing dependence on water for reproduction.
Concept context
Classification of plants from algae to angiosperms. Understanding plant diversity is essential for NEET.
